As a CCNA / CCNP candidate you are expected to understand the purpose and function of Spanning-tree BPDU guard. The CCNA / CCNP’s exam will ask of you to determine the purpose of the BPDUGuard (Bridge Protocol Data Unit) within the spanning-tree protocol.

MPLS appears to be the next generation of communications. There are numerous applications that can take advantage of this latest technology in being able to prioritize data packets by assigning labels to them. Of course, it’s still in the “early days”.

MPLS network is certainly turning out to be the major alternative. MPLS VPN services make it possible for businesses that did not have past total network meshed to benefit from it at this moment. Therefore, all of websites can interact with one another without more expenses, like frame relay.

I started the last chapter of the CCNP Study Guide book today which is about implementing IPv6 (IP Version 6). IPv6 is a technology developed to overcome the limitations of the current standard, IP Version 4 (IPv4). The major shortcoming of IPv4 is its limited amount of address space.

IPv6 is the successor to IPv4. IPv4 and IPv6 are the internet protocols that all networks use to communicate. IPv4 is still dominate today on the internet.

As the 2008 Olympic Games are broadcast around the world, one little known Olympic feat wasn’t performed by any athlete, but by the China’s Next Generation Internet project (CNGI). CNGI launched a cornucopia of fixed and mobile broadband technologies over the new Internet Protocol version 6 (IPv6) to demonstrate China’s technology advancement to the world. With government mandates and subsidies supporting IPv6 transition in China, South Korea, and Japan, as well as skyrocketing Internet use in those regions, the question is will China and the rest of Asia leapfrog America and Europe in advanced communication technologies.

In a nutshell, the Cisco IOS “Line configuration” command named “ipv6 access-class” performs the same function as its predecessor the “access-class” command; except that it is IPv6-specific. In other words, the “ipv6 access-class” Line configuration command is used to filter incoming and outgoing connections to and from a router based on an IPv6 access list.

Now in order, to get a Cisco router’s downstream interface to act like a Delegating Router (DHCPv6 Server) that performs Prefix Delegation for a specific Requesting Router (DHCP Client); and also for a group RR’s (DHCP clients) by using a DHCP for IPv6 configuration pool, you will need to complete the following 10 steps: 1. Router…

The switch to IPv6 is on. In June 2008, the U.S. federal government, which is arguably the world’s largest single enterprise, required that all its executive agencies add IPv6 to their network backbones. The European Commission recently set an IPv6 target adoption rate of 25 percent by 2010, and the chairman of the Asia Pacific Network Information Centre predicted that all IPv4 addresses will be depleted by 2011, forcing wide-scale IPv6 adoption.

Well, since this article is sort of lengthy I’m going to get right down to it; so without far ado let’s begin. The “dns-server and domain-name (IPv6)” commands are…..
